svg-deep-link

deep-svg

Vanilla javascript and Web Component wrapper, using no dependencies for an svg pan zoom and deep linking. Interactions for making every text clickable and highlatable. Deep Linking allows links winthin html pages, why not generalise this to the text inside svg and without having to edit the svg ? Each tspan is enriched with a click event, and the highlight function uses an animated svg filter.

Gif Demo

Usage

as a vanilla javascript module

import * as svgm from "../src/index.js";

let svg = await svgm.createElement(document.body,{src:"/demo/diagram.svg",id:"diagram_a",enable:true});
svg.addEventListener('text_click',onTextClick);
svgm.highlightText(svg,"Rollup");

as a web component

Note that html() is a 3 line helper function and /*html*/ helps lint the html text with the 'es6-string-html' plugin

import "../src/deep_svg.js";

const src = "/demo/diagram.svg"
const deep = html(document.body,/*html*/`<deep-svg id="id1" src=${src} enable="true" />`);
deep.addEventListener('text_click',onTextClick);
deep.highlightText("Rollup");

SVG Filter Animation

The highlight is animated through a morphology filter to create a smooth effect. The dialate operator radius is animated before the Gaussian blur is applied to it.

Caution : This is vanilla javascript. Note that the function anim_wave() is a generic function that can be placed in any section and starts animating the passed attribute patemeter.
